Glan Agua Ltd. awarded the Letterkenny Regional Water Supply Scheme including Creeslough WTP contract

Glan Agua Ltd. have recently been awarded the Letterkenny Regional Water Supply Scheme including Creeslough WTP contract. This contract consists of the Design, Build and Operation of a new water treatment plant at Goldrum serving the Letterkenny region (9,000m3/d), a new water treatment plant at Creeslough (2,100m3/d), new raw water rising mains, connection to existing raw water and treated water mains and other associated Works.

The plants are designed to the highest standards including coagulation, flocculation, clarification and filtration followed by UV disinfection. The plants have also been designed utilising BIM, incorporating smart data into the design to enhance and optimise the design, build and operation phase. As part of the design, Glan Agua created full 3D models of plants, which allowed clash detection simulations to be analysed and also enhanced the visual presentation of the project with walk-throughs of the plant created. Glan Agua Ltd continued focus on developing and incorporating innovative solutions into our design and build solutions, has ensured that the design for Letterkenny and Creeslough will provide a modern and robust treatment plant, and allow for a cost effective operation and maintenance phase for our Client and the consumers of the Letterkenny Regional Water Supply Scheme

This large-scale project will safeguard the drinking water supply for the existing Letterkenny and environs population and provide for economic and population growth into the future. The works will ensure that both the Letterkenny Regional and Cresslough Water Supply Schemes will comply with EU drinking water directives as well as Irish regulations in an area where there is strong industrial, agricultural and tourism activity.

The project also includes the replacement of 4.5km of raw water main from Lough Keel to the new plant at Goldrum, upgraded pumping stations at Lough Keel and Lough Greenan, the construction of 1.5km of trunk water main and 1.1km of distribution main from Goldrum WTP. Once completed these works will lead to the decommissioning of the old Letterkenny and Creeslough water treatment plants.


Commenting on the project, David McLoone, Irish Water’s Infrastructure Programme Regional Lead for the North West Region said “Both the Letterkenny Regional and Creeslough Water Supply Schemes are currently on the Environmental Protection Agency’s (EPA) Remedial Action List (RAL) and this significant investment by Irish Water will ensure the scheme’s removal from that list subject to approval by the EPA as well as the removal of Church Hill and Rathmullan water supplies.”


Glan Agua Ltd managing director Karl Zimmerer commented “The award of this contract continues our expansion into the water services sector, and we look forward to working closely with Irish Water, Donegal County Council, and various stakeholders in delivering this important asset safely and within the timescales required. Our sister company Mota Engil Ireland Construction (MEIC Ltd) will deliver the extensive civil engineering elements of the contract, and this further reinforces the commitment of the Mota Engil Group within the sector in Ireland.”


The design build contract is for a period of 2 years with an operations service period to follow the substantial completion of the design build works. Glan Agua Ltd. are looking forward to working on this project and with all the vested parties including the Customers, Irish Water, Donegal County Council, Nicholas O’Dwyer Ltd. and our civil and structural partner MEIC Ltd.


Luis Moreira da Silva, Glan Agua Board Director commented “With 10 years doing business in Ireland, Mota-Engil Group is now an established and recognized brand and much of that recognition has been granted through Glan Agua’s business. The Letterkenny Regional Water Supply Scheme award fits the nationwide main player role in the water industry that Glan Agua intends to play and it’s more proof that the relationship with Irish Water based on straight collaborative approaches is fruitful for all those involved and more importantly for the Irish communities.”
